Limited to running and light skills, Mitchell continues to build up strength in his right shoulder that required a reconstruction in October after he re-injured it ahead of round two.

The 27-year-old isn't expected to rejoin the main squad for up to a month and will likely miss both the Hawks' pre-season AAMI Community Series fixtures on February 20 and March 6.
