Michael Vaughan has had arguably his worst summer as a player

Michael Vaughan could miss Yorkshire's final County Championship match of the season after straining a side muscle against Somerset on Saturday.

Vaughan picked up the injury bowling on the final day of the drawn match at Scarborough and also suffered soreness in his troublesome right knee.

Meanwhile, Darren Gough said his retirement could come a game early.

Missing out on Wednesday would be a setback for Vaughan as he attempts to win a spot on the tour to India.

Yorkshire director of cricket Martyn Moxon said: "Michael has got a little bit of an intercostal injury as well as his knee being a bit sore.

"It's a concern and obviously we will check him out over the next couple of days. He is obviously a doubt.

"He has worked really hard trying to get runs for us but we will just have to wait and see."

Vaughan won a new England central contract at the start of September but is by no means assured of a place on the tour of India, and had been hoping to prove his form before the end of the domestic season.

The irony is that the injury comes after he told journalists at Lord's in July that he had stopped bowling competitively because he found it was too much of a risk to his fitness.

Assuming Vaughan does not play against Sussex at Hove, it would be a controversial selection for him to then be picked for India following a run of dreadful performances for Yorkshire and England throughout the summer.

He may instead play some overseas club cricket and try to force his way into the side for the tour of West Indies next spring - much like Andrew Strauss did last winter when the Middlesex man was axed for the Sri Lanka tour but came back magnificently in New Zealand.

When I look back I'm glad my last wicket was Justin Langer Darren Gough

Meanwhile, Yorkshire captain Gough could have played his last game after casting doubt over his availability for the match at Hove.

He said: "I wanted to go out in style today - and that proved to me I am ready to retire, I am absolutely shattered now.

"I bowled as quick as I have for a long, long time in that first spell [at Scarborough]. I had the opposition saying that is the quickest they have faced all season and when they say stuff like that, I'd like to finish on that note.

"When I look back I'm glad my last wicket was Justin Langer. I've had some great battles against him and it's nice to know my last wicket in Yorkshire was someone as good as him."
