IRVING, Texas (AP) _ Washington tight end Stephen Alexander and cornerback Fred Smoot, and Dallas receivers Joey Galloway and Reggie Swinton all left the first half of Monday night's game with leg injuries.

Cowboys fullback Robert Thomas was injured in the fourth quarter after making a 6-yard catch. Thomas never got up after the tackle and his lower left leg was immobilized in an air cast while he was still on the field.

Swinton, the Cowboys' best kick returner, strained his right hamstring during pregame warmups. He fielded the game's opening kickoff, but left soon after.

Alexander, who made the Pro Bowl last season, sprained his right ankle while blocking on a running play in the first quarter. X-rays were negative, but he was not expected to return.

Galloway went down next, spraining his left ankle on a pass that was intercepted by Smoot. Galloway, who missed last season with a knee injury, was hurt while landing on the play.

Smoot sprained his left knee later in the second quarter when he was blocked by Dallas receiver Darrin Chiaverini.

Without Swinton or Galloway, Dallas' only healthy receivers were Chiaverini and Raghib Ismail, who was back in the lineup for the first time since spraining a knee in Week 2.
