Tommy Hunter could be sidelined six weeks with a strained right groin.
As groin strains go, it appears to be on the more serious side. He'll return to Texas to receive a blood-platelet injection before beginning his rehab. Though Hunter's 13-4 record and 3.73 ERA last season were pretty fluky, it's still a blow to the Rangers. Dave Bush and Michael Kirkman are the candidates to replace him in the rotation. Kirkman definitely has more upside of the two, but the Rangers would probably prefer giving him some more Triple-A seasoning.
