Scottish Championship side St Mirren have completed the signing of Keith Watson.

The defender, who was released by Dundee United at the end of last season, has agreed a deal with the Paisley-based club that will run until January 2016.

"It's been a long summer and I'm absolutely delighted to come here, do well for St Mirren and hopefully get as much games as I can," the 25-year-old told the club's official website.

"I done quite a bit of training with Hibs over the summer and got quite a lot of running there and I was also in Aberdeen for a couple of weeks and trained with them so I think my fitness will be fine. I haven't played any pre-season friendlies but hopefully I can get into the team and that'll come through games."

Watson has been assigned the No.20 shirt for his stint with the Buddies.
