The play in question happened with the second batter of the game. Brennan Boesch grounded out to short, but replays showed it was a very close call as to whether he beat Mike Aviles' throw.
Brookens immediately exchanged words with Nelson on the call, and he then continued it later in the inning. Once Brookens took the field again for the second, he apparently picked up the argument with Nelson, who promptly tossed him before the Red Sox's defense was in place.
Infield coach Rafael Belliard quickly jogged out of the Tigers' dugout to take Brookens' place in the first-base coaching box.
It came exactly a week after Brookens was ejected by first-base umpire Paul Emmel in Cleveland for arguing that Indians pitcher Justin Masterson balked with a runner on first. Replays showed Masterson never came set before going into his delivery.
Brookens said earlier this week that Emmel had warned him that he wasn't going to hear any more arguments and then promptly tossed Brookens after the next thing Brookens said. Brookens said he did not use a curse word.
Neither Brookens nor the Tigers' staff knew if umpires were operating under a new philosophy on not allowing continued arguments, but the same stance seemed in place when third-base umpire Tim Tschida ejected third-base coach Gene Lamont on Monday.
"There does seem to be a limited tolerance," Brookens said Tuesday.
The Tigers have to wonder. Manager Jim Leyland and members of his coaching staff were ejected six times on their 10-game road trip.
Leyland said after the game that he would pay Brookens' fine.
