"He looked in good condition, he didn't aggravate any injuries and he played very well tonight," says Roger, who oversaw a 3-3 draw at Leicester.
"I would think he would be looking at another couple of games to get to full fitness; there is nothing like games to bring that up.
"I am struggling to remember the last games he played but he did very well tonight and he has got the ability to make a real contribution to the season."
West Ham were a goal down after two minutes - "a foul on Blewitt that the ref didn't see" was Roger's verdict of the build up to the goal - but equalised when David Noble played a through ball which allowed Greg Pearson to draw the Leicester keeper to score.
But a penalty decision five minutes into the second half allowed Leicester to take the lead once more.
"The lads are disappointed and it looked like their player, Stuart, simply miskicked it," says Roger.
"The third goal from them looked offside as well although it is just possible Brent Tattum played them on."
But Don Hutchison made it 3-2 from the spot before a good move involving him, David Noble, and Shaun Byrne, set up Daryl McMahon to score the equaliser.
"I thought that young Greg Pearson played his best game for us in the reserves and he stuck away his goal very well," adds Roger.
"He worked very hard and did some good things.
"We had a very young back four who were at full stretch against a very decent Leicester side.
"When you think that the first goal was a foul and the second was a penalty I was very happy with the defence, and Steve Bywater made some good saves - I was happy with him as well."
