Sam Walker admits that his Colchester United future is “up in the air,” as the end of season approaches.

Walker became only the third-ever keeper to pass 200 league appearances for the U’s last Saturday, although he was disappointed that his landmark game was marred by a last gasp defeat at Lincoln City.

Walker followed in the footsteps of Mike Walker (451 league games) and Percy Ames (397), two U’s legends, by clocking up his 200th league match in a U’s shirt at a sun-kissed Sincil Bank.

But the 26-year-old was powerless to prevent the Imps from snatching an injury-time winner, through substitute Luke Waterfall’s header, a result which finally killed off the U’s lingering League Two play-off hopes.

His current contract expires this summer, although he is in talks with the Essex club about a possible new deal.

“I’m pleased to get that landmark 200th league appearance out of the way, but it was a disappointing result, to concede so late in the game,” said Walker.

“It was a game in which I thought we performed very well. We dealt with everything that they threw at us, and maybe we could have got more than the one goal ourselves.

“We needed the win today, and when they got a man sent off (Michael Bostwick) you thought maybe this was going to be our day. As it was, it turned out to be their day, which is kind of where we are at, at the moment.

“It’s been a season of fine margins, and this match summed up our season.”

Walker first arrived at Colchester, on loan from Chelsea, in January, 2013, and U’s fans will be hoping that he chooses to extend his stay into a seventh season at the club.

“It feels like forever ago, since I first arrived, with lots of ups and downs,” explained Walker.

“I’m pleased to maintain that level of fitness, barring that (2015-16) season out injured. It’s something I am very proud of, maintaining consistency levels and my fitness level.

“My long-term future is up in the air at the moment.

“I have had conversations with the club, but my focus for the last six months has been playing each game, with the idea of getting us into the play-offs. I will now be focusing on our last two games.”
