The team ruled out Robinson on Saturday as the veteran has been in the league-mandated concussion protocol since reporting to team headquarters on Wednesday with concussion symptoms.
The good news, as it were, is that since Robinson did not practice all week the Browns have had time to give the first-team practice reps to another player, presumably Justin McCray, who started the game against the New England Patriots on October 27 after Robinson was benched for poor play.
The bad news is that while Robinson is not very good - his season grade of 66.6 from Pro Football Focus puts him at No. 50 on the rankings of the league’s offensive tackles, according to cleveland.com - McCray actually played worse in his lone start of the season. In that game against the Patriots, McCray earned an overall grade of 32.3, a pass-blocking grade of 22.8 and a run-blocking grade of 49.2 from Pro Football Focus.
Whoever lines up at left tackle will be dealing with Pittsburgh linebacker Bud Dupree, who has seven sacks and 10 quarterback hits on the season. Four of those sacks have come in his last five games, with the only game in that stretch where he did not record a sack coming against the Browns on November 14.
