According to the Pittsburgh Post-Gazette, the Steelers don't yet have a concrete idea of when Heath Miller (knee surgery) will be ready to return.
Miller tore his ACL, MCL and PCL in Week 16. Miller's ACL and MCL both required surgery. Miller's teammate Rashard Mendenhall was able to avoid the PUP list last season after shredding his knee in Week 17 2011, but the PUP is still Miller's best bet to begin the year. With Miller now on the wrong side of 30 in addition to rehabbing his knee, tight end could be a priority for Pittsburgh in the draft.
