Tomkins dislocated his shoulder in the gym last month and has undergone successful surgery.
“Hopefully it will not set me back and I will be able to play a couple of games before the end of the season, you never know,” he said on whufc.com.
“It depends on how well it goes. I’m preparing myself mentally that I won’t play again this season, so if I come back earlier then it’s a bonus.
“I was in the gym doing some exercises like I normally do, but just went a bit too far with one of them and unfortunately I dislocated my shoulder.
“I’d have been frustrated if I had done it on the pitch, so to do it in the gym made it even more frustrating.
“I had the operation about two weeks ago and it has settled down. I’m progressing with my rehab and getting more movement and hopefully I can get back as soon as I can.
“When you look at the fixtures, we have got quite winnable games, so I am confident the lads can get a lot of points from them with the squad we have got.
“I hope the lads stay injury-free and can push on and secure at least a top-half finish – that’s definitely our aim.”
