Starting an injured kicker

Patriots kicker Nick Folk is currently questionable for the Sunday night game against the Buccaneers. He is dealing with a left knee injury (planting leg). the fact that the Patriots have not added any other kickers to the active roster suggests that Folk will play. However, it is possible that the injury will affect his kicking ability as well as the opportunities he is given. What is your experience with starting kickers dealing with lower body injuries? Is it best to avoid at all costs or safe to trust?
