TwelfthMan: My account
Anthony McGrath takes over the captaincy from Darren Gough for their LV County Championship match against Sussex at Scarborough this week.
The veteran seamer is being rested ahead of two crucial NatWest Pro40 games next week and his place in the squad has been taken by Steven Patterson who took eight wickets for the second XI last week.
Tim Bresnan could be made available for Yorkshire from the second day of the fixture if he does not play for England in the final match of the NatWest Series.
Richard Pyrah and David Wainwright are the only other additions to the team which drew with Kent in a nail-biting finish a week ago.
Michael Vaughan continues his return to championship action after missing the NatWest Pro40 match against Glamorgan at the weekend.
Mohammad Sami is set to make his Sussex debut in the match against Yorkshire after signing for the club as an overseas replacement for the retired Mushtaq Ahmed.
He comes into the squad in place of Will Beer, with Corey Collymore replacing James Kirtley from the XI which played against Nottinghamshire last week.
Ragheb Aga and Rory Hamilton-Brown make up the 13-man squad, but are unlikely to play unless there is an injury on the morning of the match.
Matt Prior and Luke Wright are away on England duty, meaning Andrew Hodd will keep wicket once again.
