Washington ? Simmering all year, the antagonism between Albert Haynesworth and Mike Shanahan finally reached the boiling point Tuesday when the two-time All-Pro defensive lineman was suspended by the Washington Redskins coach without pay for the rest of the season.

Citing a litany of acts that essentially add up to season-long insubordination, the Redskins suspended Haynesworth for “conduct detrimental to the club” and told him he’s not welcome for the team’s final four games — and making it extremely unlikely he will play for the club again.

“Despite the club’s numerous attempts to persuade Albert Haynesworth to abide by the terms of his contract, he has repeatedly refused to cooperate with our coaching staff in a variety of ways over an extended period of time,” Shanahan said in statement released by the team. “Among other things, he has consistently indicated to our defensive coaches that he refuses to play in our base defense or on first-down or second-down nickel situations. He has also refused to follow the instructions of our coaches both during weekly practices and during actual games as well.

“Yesterday, when Albert was at Redskin Park, he told our general manager Bruce Allen that he (Haynesworth) would no longer speak with me. Although suspending any player is not a decision that a head coach enters into lightly, I believe the situation has reached the point where the club clearly has no alternative.”
