First-half recap: Cowboys lead, 20-7

ARLINGTON, Texas -- The Cowboys have done a nice job in a sleepy game in which they lead, 20-7, at halftime against the Washington Redskins.

Here are some highlights:

Injury update: The Cowboys have lost two defensive players to concussions: Sean Lee and Gerald Sensabaugh. Lee was injured on a second-quarter kickoff and Sensabugh was hurt on defensive play. Both players will not return. Lee was replaced by Kenwin Cummings, who was just signed to the team on Dec. 8. Sensabaugh, who has battled a quad injury the last two weeks, was replaced by Barry Church. The Cowboys' next game is Saturday at Arizona and with a shorter than normal week, it's possible both players might not play on Christmas Day.

Witten reaches milestone: With six catches for 85 yards with one touchdown, tight end Jason Wittne has 601 catches in his career. He's become the fourth tight end in league history with over 600 catches. Tony Gonzalez (1,057), Shannon Sharpe (815) and Ozzie Newsome (662) are the others.

Sam Hurd gets the start: With Roy E. Williams out with a groin injury, Sam Hurd started, and he finished the first half with three catches for 26 yards. Hurd also has done a nice job on special teams with two tackles. Hurd has been waiting for his chance to get some playing time on offense because he's in a contract year. Hurd doesn't want to be considered a special teamer. He wants to be known as a receiver, but hasn't gotten the chance due to the development of Miles Austin and the emergence of Dez Bryant.

Buehler misses a easy one: Of David Buehler's seven missed field goals this year, three have come from within 30-39 yards. Buehler was wide left on a 35-yarder with two seconds left in the first half. It was Buehler's first miss since missing a 48-yarder at Indianapolis.

Offense doing OK: Other than getting stopped on four chances inside the 5 and the missed field goal by Buehler, the Cowboys' offense is doing a nice job. Jon Kitna has thrown two touchdown passes and the offense has gained 281 yards compared to the 116 of the Redskins.
