Anderson ruled out of final Test against India
Lancashire bowler James Anderson has been ruled out of England's fifth Test against India in Chennai.
England's leading wicket-taker had been out since August with a shoulder injury before returning to play the second Test of the five-match series in India.
"Unfortunately, Jimmy is ruled out. He's picked up some body soreness from the last game and he's not going to be risked in this game," Cook said.
"Obviously we'll make a decision on Broady after this training session. We can't do a huge amount of a net stuff, but we're going to do some fielding and a run around to get ourselves going. We'll pick the team from there.
"It's just not worth the risk with him (Anderson), especially over the past six months or so. When he's been in this situation and we've played him, he's picked up niggles and injuries.
"This doesn't seem the right time to play him. He is sore from the previous game and we don't see as a management group it's worth taking a risk.
"Could he get through? Yes, he possibly could get through. But recently over the last six months, unfortunately when we've played him here, he's picked up an injury from it. It doesn't seem worth the risk in this game."
