That is unfortunate. He’s always been one of my favorite actors, although some of his more recent movies have not been as good.
The last 4-5 years, he's only made "geezer teasers," straight to video films the feature a big star on the box even though they're only in it for a few minutes. He wouldn't learn any lines; you can even see the earpiece in every closeup. His contracts were $1 million for one day of work, and they needed to be filmed near his home. It's why Stallone cut him from the the Expendables franchise.
