Robertson in line for Sunday start

Just got back from Tigers clubhouse, where not surprisingly, Nate Robertson appears to be in line for that Sunday start at Minnesota in Jarrod Washburn's place. Jim Leyland said Robertson is scheduled to throw an extended bullpen session Thursday, which should determine whether he feels well enough to start. If he can go, the Tigers are set in their rotation. If he can't, well, Leyland hasn't said it, but one would think he might have to revisit his plans for Zach Miner at that point.
