Oxford United have completed the signing of midfielder Mark Wilson on a deal until the end of the season.
Wilson has most recently been on the books of Championship outfit Doncaster but joins the U's as a free agent.
The 32-year-old, who spent a month on loan at Walsall earlier this season, has made 10 appearances in all this term but has not played a competitive match since Rovers' 3-2 defeat at Millwall on November 29 last year.
Wilson told the club's official website: "I came down on Friday and was really impressed with everything about the club.
"I went to the game at Burton on Sunday and thought they played really well in the second half. There are clearly some very good players and they are a good bunch of lads.
"I am looking forward to playing a part here."
