Cardinals vs. Raiders 2015 live stream: Time, TV schedule and how to watch online

Cardinals head coach Bruce Arians was noncommittal earlier this week when asked whether starting quarterback Carson Palmer would play against the Raiders in Oakland Sunday night. Given how porous the Cardinals' offensive line has looked so far this preseason, it would probably be wise if Arians just put the oft-injured Palmer in bubble wrap in order to preserve him for when the games start to count.

The Cardinals' line has been decimated this summer, beginning with left guard Mike Iupati's knee injury that will keep him out for at least six weeks. Also, right tackle Bobby Massie was suspended for three games earlier this month for violating the league's substance abuse policy.

Palmer was sacked twice last week in Arizona's 22-19 loss to the Chargers, and Cardinals QBs were sacked a total of six times in the game. Even though Palmer is one of the top quarterbacks in the league, he's not the most mobile of athletes and he has an extensive injury history. The Cardinals have gritted their teeth and found success in the wake of major quarterback injuries, but it sure would make things easier if Palmer stays healthy this season. He doesn't really fit the bill of a guy who needs a lot of preseason reps.

The lone offensive bright spot for Arizona last Saturday was running back David Johnson, who rushed for 66 yards on 13 attempts. Arians is probably interested in getting an extended look at his depth chart for the final two weeks of the preseason, given the rash of injuries Cardinals players suffered at the end of last year. Arizona's running back position has been lackluster for some time, but this year's rookie class was one of the strongest we've seen in a long time. Johnson has been showing the Cardinals he absolutely belongs in that class, and should get a chance to do it again in this game.

The Raiders are coming off a lackluster preseason performance as well, losing 20-12 to the Vikings last Saturday night. Teddy Bridgewater completed 10 of 14 passes against the Raiders' defense, but only managed to throw for 89 yards. The Raiders' pass defense has allowed the 10th-fewest yards in the league through the first two weeks of the preseason. Newly acquired veteran safety Taylor Mays was added to the roster this week.

But arguably the lead story out of Raiders training camp so far has been the performance of some of the club's potentially dynamic young receivers. Derek Carr and first-round pick Amari Cooper connected for a pretty 40-yard over-the-shoulder completion last week, and wide receiver Brice Butler has impressed as well. Butler leads the Raiders in overall production at receiver over the last three preseasons.

Carr showed flashes of competence in his rookie campaign. But with the weapons at his disposal -- Cooper in particular -- the Raider's offense could make some big plays this season. Michael Crabtree and Cooper could combine for an explosive duo and any extended reps Carr gets with them can only help.
