Just one week after Jaguars head coach Mike Mularkey told media that he doesn't want Justin Blackmon to get frustrated, he admitted on Monday that the rookie has been "pressing" and "getting a little frustrated" with his lack of production three weeks into the season.

After 10 receptions for 136 yards and one touchdown in limited time during the preseason, Blackmon has failed to parlay that success into regular season production, catching just four of 15 targets in his direction for 31 yards.

"He's pressing a little bit," Mularkey said during his Monday press conference. "He's getting a little frustrated that he'd like to be more productive."

The No. 5 overall selection in the 2012 NFL Draft has been one piece of a passing offense that has struggled mightily in each of the last two weeks. During the two games against divisional opponent, Blaine Gabbert has managed just 208 yards passing, a number that would have been much worse had an 80-yard touchdown pass to Cecil Shorts III not saved the Jaguars from an 0-3 record.
