SAINTS loanee Billy Sharp could be playing for his Doncaster future this weekend.

The striker rejoined his former club in the January transfer market, having fallen totally out of favour at St Mary’s.

Doncaster would like to make the move permanent, but are facing relegation from the Championship on Saturday.

They will be demoted from the second tier if they fail to win at champions Leicester and Birmingham win at Bolton. As such, they might not be able to afford Sharp permanently, and the player might not want to drop down into the third tier anyway.

If Doncaster lose at Nigel Pearson’s table toppers, Birmingham will only need a point to avoid a second relegation in four seasons.

Sharp, above, contracted to Saints until summer 2015, has scored four goals in 15 Championship games since returning to Rovers.

But he has only netted once in his last nine games, with his latest blank coming against the manager who signed him for Saints, Nigel Adkins.

Rovers were beaten 3-1 at home by Adkins’ Reading last weekend, and would have fallen into the relegation zone had Birmingham got at least a point at home to Wigan on Tuesday instead of losing 1-0.

Sharp had a loan spell with Adkins at the Royals in the first half of this season, scoring twice in an injury-hit spell.

Sharp’s last Doncaster goal was in a 2-1 win at Leeds on March 29, after which they sat eight points clear of the drop. “We thought we'd got out of the relegation battle when we had an eight or a nine-point gap on the bottom three,” Sharp said.
