Marquis Brown's NFL debut was one of the most impressive by a receiver in recent memory. Unfortunately, the Baltimore Ravens rookie may be a bit hobbled as he tries to replicate that historic performance in Week 2.

Brown is listed as questionable for the Ravens' game against the Arizona Cardinals on Sunday as he continues dealing with nagging foot issues. Coach John Harbaugh, though, said on Friday that each of the five players currently deemed questionable for Sunday's contest are expected to play, as noted by Pro Football Talk's Charean Williams.

The University of Oklahoma product was one of the breakout stars of Week 1. Despite playing just 14 snaps due to foot pain that caused him to miss much of the Ravens' offseason activities, Brown exploded against the lowly Miami Dolphins, catching four passes for 147 yards and two touchdowns in Baltimore's 59-10 victory.

What's especially scary for opponents is that the notoriously speedy Brown insists he wasn't running at full capacity in the Ravens' season-opener.

“That was, like, nowhere near my top speed,” he said, per Jonas Shaffer of The Baltimore Sun.

Brown, the cousin of six-time Pro Bowler receiver Antonio Brown, suffered a Lisfranc injury to his right foot in the Big XII championship game, undergoing surgery in February. He was unable to participate in the NFL Draft combine and the Sooners’ Pro Day as a result, but boasted he would have broken the record for the 40-yard dash, 4.22 seconds, held by the Cincinnati Bengals’ John Ross.

We'll find out on Sunday if Brown, despite still being somewhat limited, is a bit faster than he was against the Dolphins.
