I'm playing with Forest and have Chris James on loan from Fulham. In the beginning of January he gets that [Rst] sign, so I drop him for some games until he's ready to go again. A month goes by, he's still in need of a rest. So I give him 1 week off training. I check after 6 days, still in need of a rest. And, on the first day back in training he gets injured for 3-5 months.
I have rested players before just by dropping them form some games, and they have been fine after that. Just thought I'd post this because I haven't encountered something like this before.
