Former Ipswich Town and Sunderland striker Connor Wickham is training with Preston North End, following his exit from Crystal Palace this summer.
The 28-year-old has played just 33 league games in the past four seasons, although he missed all of 2017-18 with a cruciate ligament injury.
Wickham scored two goals in 13 games on loan at Sheffield Wednesday in 2019-20, but did not feature at all last season.
"He's in and he's training," boss Frankie McAvoy said.
He told BBC Radio Lancashire: "He's not played a lot of games. We need to look at him, see how he does and see if he can come and do a role here.
"If he can then we'll look to sign him. If we don't then we'll be honest with him."
