Steven Finn is bowling well enough to step into England's attack if required during the Ashes, according to Middlesex captain James Franklin.
The fast bowler, 26, last played Test cricket in the first Test against Australia at Trent Bridge in July 2013.
"He is bowling as well as he has ever bowled," Franklin told BBC London 94.9.
"It will be comforting for England to know they have got Steven waiting in the wings if someone loses a bit of form or falls over with an injury."
Finn was named in an unchanged squad for the second Test of this summer's Ashes series, which begins at Lord's on Thursday.
England's pace attack of James Anderson, Stuart Broad and Mark Wood has been settled in recent Tests but Finn was a regular in the One Day International and Twenty20 series against New Zealand last month.
Watford-born Finn has played seven matches for Middlesex in the County Championship this summer, and took 4-41 in the draw against Somerset this week before being replaced by James Harris so he could link up with England.

Franklin believes Finn's recent performance against Somerset showed "good signs" for England.
"It was an amazing day for his bowling," the 34-year-old New Zealander said.
"He was swinging the ball out beautifully, which we haven't seen a lot of, and bowling fast. I wouldn't have wanted to be batting against him.
"It will be interesting to see if England use him at some stage in this Ashes series. They are 1-0 up and their bowlers are doing a great job for them.
"If he doesn't end up playing for England in the next few weeks hopefully he can keep his form up with us and keep banging down the door for England."
