Covolan spent his early career with Trieste in his native Brazil. He was scouted by Vasco da Gama. After impressing on a two-week trial, he signed a professional contract at Vasco at 17.[6] He acted as the practice goalkeeper for Juninho Pernambucano's free kick training sessions, later recalling that such was the player's ability that "I was basically just a cone".[7] He returned from Rio de Janeiro after three years to sign with boyhood club Atlético Paranaense.[6] He later recalled that Atlético had eight goalkeepers on their books and that he realised halfway into his three-year contract that he would never play a first-team game for the club.[8] He tried to gain experience in senior football by leaving on loan but was injured in a warm-up exercise and sidelined for four months.[6]
Covolan moved to Spain later in 2014 and joined Tercera División team Atlético Rafal. He switched to fellow Mallorcan side Alaró the next year, making 35 appearances. He left the club following the death of head coach Julián Ronda.[7] He spent three months on trial at Mallorca but was deemed to be too old at the age of 24.[6]
He moved to Torquay United in May 2019 after impressing managerGary Johnson on trial.[19][20][3] He competed with Shaun MacDonald for a place in the first-team, but had to wait for his opportunity after picking up an injury in pre-season, making his first-team debut in a 2–1 win at Dover Athletic on 17 August.[3] Covolan would play 25 league games in the 2019–20 season, with MacDonald playing the remaining 11 league matches in a season that was cut short due to the COVID-19 pandemic.[1][21][22] He featured 26 times in the 2020–21 campaign, whilst MacDonald played 19 league games, as Torquay qualified for the play-offs with a second-place finish.[1][21] On 20 June 2021, he scored an injury-time equaliser against Hartlepool United in the National League play-off final, which Torquay eventually lost on penalties, despite two saves from Covolan.[23] His goal earned him comparisons to compatriot Alisson, a goalkeeper who had scored a headed goal for Liverpool earlier in the year; the pair had actually played against each other some years earlier in a tournament for under-23 players when Atlético Paranaense came up against Internacional.[24]
Port Vale
On 23 June 2021, he signed a two-year contract with League Two side Port Vale; manager Darrell Clarke said that "he is hungry to prove he’s a league-level player and we feel he has all the attributes to succeed at this level".[25][26] However, the move would turn out to be the "lowest point" of his career as he struggled to handle the pressure of league football and suffered with depression as a result.[7] Having already been shown a red card in a pre-season friendly, he was sent off on his English Football League debut after rushing off his goal-line to trip Nicke Kabamba during a 1–0 defeat at Northampton Town on 7 August.[27][28] He returned after a serving a one match suspension and kept four clean sheets in his next seven games, saying that "you learn from every mistake and that is what makes you stronger".[29] He was criticised by Clarke for an error during a win over Barrow on 16 October, but responded by saving a penalty in a 1–1 draw with Mansfield Town three days later.[30] On 15 January 2022, he was sent off for kicking out at Swindon Town's Harry McKirdy after the pair jumped for a high ball moments before half-time during what would finish as a 3–1 home defeat; a furious Clarke said after the match that "he has got to learn from that otherwise he won’t be staying at the club for very long".[31] Covolan, who was suspended for four games for the incident, was supported by captainTom Conlon, who said "he's one of us, he is a big part of the squad, the boys love him to bits".[32] He was an unused substitute as Vale secured promotion out of the play-offs with victory over Mansfield Town in the final at Wembley Stadium.[33] He played 22 games in the 2021–22 season, keeping seven clean sheets.[34]David Flitcroft, the club's director of football, confirmed that the player's contract would not be renewed beyond June 2023.[35]
Chesterfield (loan)
On 5 July 2022, Covolan returned to the National League to join Chesterfield on a season-long loan deal.[36] On 6 August, he made his debut for the Spireites in a 2–2 draw with Dorking Wanderers, receiving a red card after 28 minutes for an "off the ball incident".[37] Manager Paul Cook had stern words for Covolan after the match, saying that "it is something that Lucas will learn from quickly [and] if he doesn’t learn quickly he won't be at the club, it is that simple".[38] Covolan was returned to the starting eleven after Ross Fitzsimons stood in during his suspension, and by September was linked with a permanent move to Chesterfield.[39] However, after making eight further starts he was sidelined with an ankle injury, whilst during Covolan's absence Fitzsimons was praised for his good form.[40] He was not named in the 2023 National League play-off final matchday squad for the defeat to Notts County.[41]
Maidstone United
On 4 August 2023, with less than 24-hours until the start of the 2023–24 season, Covolan signed with newly-relegated National League South club Maidstone United.[42] Maidstone defeated EFL clubs Barrow and Stevenage to reach the fourth round of the FA Cup, where they then knocked out Championship side Ipswich Town 2–1 at Portman Road, with Covolan named as man of the match having made a "string of saves" to help pull off the upset.[43] Manager George Elokobi said that Covolan was the best goalkeeper in the National League South.[44] He played every league game as Maidstone finished the 2023–24 season in fourth place, qualifying for the play-offs.[1] He was an unused substitute in the 2024 Kent Senior Cup final victory over Ebbsfleet United.[45] His teammates voted him as Players' Player of the Year.[46] He was offered a new contract in May 2024.[47]
