Ruckert wasn't targeted in Monday's 32-19 loss to the 49ers.
Tyler Conklin's two targets accounted for all of the pass-catching opportunities afforded to Jets tight ends in the season opener. Ruckert played 33 percent of snaps on offense to Conklin's 90 percent, so it would likely take an injury to Conklin to clear the way for Ruckert to see significant playing time.
