The former Preston North End skipper has been fired by Salford City
Clarke joined the Ammies last summer after seven years with North End.
Despite signing a two-year contract when he arrived at Salford, the 33-year-old is one of 13 players released by the League Two side.
Others to be released include former Manchester United striker James Wilson and former Burnley midfielder George Boyd.
Clarke was an extremely popular figure during her long stay in Deepdale.
The defender announced himself in style by scoring the PNE winner in the League Cup win over Blackpool in August 2013 – his second game for the club.
He made 247 appearances for North End, scoring 15 goals.
In 2015, Clarke skipped PNE when they beat Swindon 4-0 in the Ligue 1 play-off final at Wembley.
He left Deepdale last July at the end of his contract – deciding not to sign a short-term extension to cover resumption games at the end of last season.
At Salford, Clarke started 29 games and six substitutes. He was on the side that won the Papa John’s Trophy at Wembley in April – postponed from last season due to the pandemic.
They missed the Ligue 2 play-offs, finishing eighth, having had three managers in charge during the season.
