Tony Pulis: "We will review it at the end of the season with Dean Whitehead and three or four others.
"It will help his cause if he is in the team, of course it will. Michael wants to play. He wants to play every week.
"I haven't got a player in that dressing room that doesn't want to play. There is no-one in there happy to just sit and pick up the money.
"We needed to get Michael games, but over Christmas was difficult because there was so much going on.
"But once we got that out of the way we arranged two or three games, which he was part of.
"There is no clause in Owen's contract guaranteeing him a second season if he played a fixed amount of matches.
"No, he doesn't need to play a certain amount of games to win a contract.
"There is nothing like that in his deal. There are no strings attached to his contract."
