He was taken off injured, after an innocuous-looking fall, and was replaced by Michael Hector.Walsall, playing their ninth cup tie of the season, hardly troubled Reading early on but Tom Bradshaw went close with a 20-yard shot.The striker, linked with Reading during the transfer window, struck the ball well but it deflected off Jake Cooper and flew narrowly wide.Reading then struck twice in three minutes to give themselves a comfortable cushion at the break.In the 37th minute, Robson-Kanu collected a Chris Gunter throw-in and wriggled his way through before unleashing a fierce shot into the roof of the net from a tight angle.Five minutes before the interval, Stephen Quinn got free on the left and crossed for Vydra to stab in from close range.Vydra should have made it 3-0 soon after, when racing clear of the Walsall defence, but he dragged his effort well wide.Reading continued to press in the second half, with Robson-Kanu sending in a weak shot that goalkeeper Neil Etheridge gathered easily.Walsall gradually got their act together going forward and Romaine Sawyers was unlucky to see his 25-yard strike the crossbar, with home goalkeeper Ali Al Habsi well beaten.Left-back Andrew Taylor let fly with a 30-yard free kick but that also narrowly missed the target.Reading soon regained their momentum, with Etheridge athletically tipping a long-range Oliver Norwood free-kick on to the bar and away to safety.But they settled the outcome in the 75th minute, when Williams latched on to an error by James O'Connor and ran through to beat Etheridge.Completing Walsall's miserable afternoon, Etheridge was injured as Williams tucked the ball past him and had to be carried off on a stretcher
Substitute goalkeeper Craig MacGillivray replaced him for the closing stages.Vydra added Reading's fourth in the last minute, heading home a Gunter cross
