Mickey Joseph is working on getting Nebraska’s wide receivers up to speed in time for a Week 0 trip to Dublin, Ireland. Unfortunately, Joseph confirmed Wednesday that a pair of players were held out of practice.

According to Adam Krueger with KMTV 3 News Now, Joseph revealed LSU transfer Trey Palmer did not practice with an illness. Freshman Decoldest Crawford was also held out of practice but Joseph referred to a trainer when asked about Crawford.

Both Palmer and Crawford are trying to be key pieces for Nebraska as the offense looks to replace the production of Samori Toure who is off to the NFL. Kickoff in Week 0 against Northwestern is just a little over two weeks away, so any absence or time missed in camp is critical at this juncture.
