Jarvis, a former England international, hasn’t made a first-team appearance since May 2016 and has had to undergo operations on both his knee and ankle since joining the Canaries from West Ham United on a permanent basis in 2016.
But Keates thinks the 32-year-old former Gillingham, Wolves, and West Ham man is looking sharp and is keen to get back into action after enduring such a lengthy injury lay-off.
Speaking via the Express & Star, Keates said; "He will be in the squad for the weekend. He has been training with us this week. He has had a bad couple of years injury-wise. But he has fully recovered and he’s looked sharp in training. He now wants to play games.
"He’s had a difficult couple of years. But he is fully fit now and has been training for the last two or three months. He is a winger who gets balls into the box and I think that’ll suit us.
"It will suit the forward players, especially Cookie who likes to get on the end of crosses. He will be a great addition to the squad."
