According to The Big Lead, no band wats to play along Maroon 5 because of the fact Colin Kaepernick hasn’t been signed to an NFL team.

The Big Lead:

One would think that playing on one of the world’s biggest stages would be intensely appealing, but that’s not the case this year. Apparently Maroon 5 is having trouble lining up guests to jam with them, per a US Weekly report. But it’s not really because of anything Adam Levine-related.

“No one wants to associate themselves with the NFL” in light of its response to Colin Kaepernick’s protest against police brutality,” a source told the magazine.

It is unclear which bands have turned Maroon 5 down.
