Crows footy manager John Reid said about Bock, who is owned by almost 16,000 DT coaches, “Nathan’s improving. By about this stage next week we might be able to see how the injury’s going and he might be able to have a light run.
“On the good end, Nathan could be available for the Carlton game [in round 22], but on the bad end he might play none [of the remaining games].”
Brett Burton will miss this weekend's clash with West Coast having aggravated a corked buttock in training, while Pat Dangerfield (back) and Dave Mackay (knee) should return to training midweek and will be in the mix for selection.
Also $86k def/fwd Shaun McKernan is expected to return from a broken arm via the SANFL this weekend and could be a handy addition if he plays AFL in Round 22.
