The most talented and dependable member of the Arizona Cardinals offensive line, left tackle Levi Brown, left Friday’s preseason game against the Oakland Raiders with a triceps injury. No word on the severity, but Darren Urban of AZCardinals.com tweets this ominous note:

Regarding T Levi Brown's triceps injury: Last two triceps injuries I recall for Cards: Chike Okeafor, Bertrand Berry. Both season ending.—

Kent Somers of the Arizona Republic points out that the Cardinals’ second-team LT is not exactly experienced:

Levi Brown's backup, DJ Young, was on practice squad 16 wks last year. 1 game on roster, inactive. Brown's a big loss—

Brown was the fifth overall pick in the 2007 draft and has started every game for the Cardinals for the last four seasons, first at right tackle before moving to left tackle in 2010.
