Trent Murphy out for the season with torn ACL and MCL
Murphy was slated to miss the first four games of the season for violating the NFL's policy on performance-enhancing drugs. He'll miss two to three weeks with what one source described as a "tweaked" knee, something that dates to his days at USC.
Arsenal could be without several key players with Alexis Sanchez ruled out by injury and Laurent Koscielny suspended. But they were given a major boost, as Welbeck was able to level things up.
Leicester - not too far removed in their line-up from the team that won the title two years ago - might have gone into half time leading after Jamie Vardy snaffled Marc Albrighton's cross, but with the last kick of the half Danny Welbeck - another forward player in the competition for places - capitalised on Mesut Ozil and Kolisinac's unlocking of the Leicester defence for 2-2.
The striker, who the Gunners signed from Lyon for an initial fee of €53 million in the summer, finished clinically to put the hosts ahead after two minutes, expertly heading home Mohamed Elneny's cross.
Arsenal would hold on to secure an incredible victory in a magnificently entertaining season opener.
The visitors took the lead again 10 minutes into the second stanza as Vardy grabbed his brace with a cute header from close range. The home fans then endured the nervous wait for the late heroics, time largely passed by watching Alex Oxlade-Chamberlain fling hopeful shots at the goal.
"And you could see that this team has quality and is used to playing together, but [we had] 70 per cent possession with 27 shots on goal". Wenger names Dennis Bergkamp as perhaps the most skilled player he has ever worked with, before Mertesacker says he'd give Arsene Wenger a miniature World Cup trophy if he had to buy him a present.
"I'm happy the goals we conceded we can work on together".
