An added time goal from Luke Chambers earned Ipswich Town a 2-2 draw at Peterborough United as the Blues managed to maintain their unbeaten start to the Sky Bet League One season.

James Norwood had given the visitors a fourth-minute lead as he scored his first goal for his new club when he was on hand to easily tap in after Posh keeper Christy Pym had spilled the ball into his path.

The home side picked themselves up conceding early, though, and just before the half-hour mark were on level terms, with Ivan Toney nodding home after Marcus Maddison had played the ball into the box.

They then added to that in the 62nd minute as Mo Eisa opened his Peterborough account after pouncing on a defensive mistake and poking past Town goalkeeper Tomas Holy.

Ipswich then wasted a golden chance to restore parity when Pym kept out Norwood's penalty after Kayden Jackson was fouled in the area.

However, Posh were denied the three points by Chambers' late intervention as Paul Lambert's team salvaged a draw at the end.

It meant Ipswich were able to extend their unbeaten start to the League One season and now sit eighth in the fledgling table after three games of the campaign.

Elsewhere in Sky Bet League One, Lincoln City and Blackpool maintained their 100 per cent records with home wins.

Blackpool started the day top and made sure of a third win in as many games with a 2-1 victory over Oxford.

Ryan Edwards opened the scoring with a close range header in the fifth minute and Armand Gnanduillet doubled the advantage from the penalty spot at the end of the first half - but there was still time for Josh Ruffels to pull a goal back before the interval.

However, Lincoln displaced the Seasiders from top spot by defeating Southend 4-0 at Sincil Bank.

Jason Shackell headed the Imps into the lead just past the half-hour mark and further goals from Harry Toffolo (40), Tyler Walker (penalty, 48) and Bruno Andrade (81) wrapped up a convincing home success.

Sunderland picked up their first win of the season, coming from behind to beat Portsmouth 2-1 at the Stadium of Light.

Marcus Harness gave the visitors the lead midway through the first half but Jordan Willis powerfully headed an equaliser from Grant Leadbitter's corner five minutes later, before Chris Maguire completed the turnaround six minutes before half-time, tapping in Aiden McGeady's cross.

Tranmere picked up their first points of the season in style, beating hapless Bolton 5-0 with goals from Ollie Banks (38), Morgan Ferrier (40 and 46), Connor Jennings (63) and Stefan Payne (75).

Coventry defeated Bristol Rovers 2-0 with goals from Jordan Shipley (45) and Gervane Kastaneer (82), while Kieran O'Hara's 24th minute own goal was enough to give Rotherham victory at Burton.

David Wheeler's last minute goal gave Wycombe a 3-2 win over MK Dons. Joe Jacobson (penalty, 12) and Fred Onyedinma (37) had earlier scored for the hosts, with Jordan Bowery (32) and Jordan Houghton (penalty, 51) replying.

There was also a last minute winner for the home side at Doncaster, 3-2 conquerors of Fleetwood. Cameron John (19), James Coppinger (39) and Wes Burns (90) scored for the hosts, with Conor McAleny (10) and Paddy Madden (56) replying.

Luke O'Neill gave AFC Wimbledon the lead at home to Accrington three minutes before half-time but Colby Bishop's 64th-minute reply earned Stanley a point, after they had Zaine Francis-Angel dismissed for two yellow cards.

Shrewsbury and Rochdale finished goalless.
