He had a good run for the Cats, but the linebackers haven't been a strength for the Cats for a while and the last game was probably the final straw. Somebody could pick him up for another season, but he appears to have lost a step.
One of my favourite players during his good years, as he always seemed to be making the big defensive play, whether it was a forced fumble, blocked punt or timely sack. Sometimes in football you can't be very sentimental. Linebackers careers often don't last that long and there's always another crop of imports coming up from the US every year. Farewell Markeith. Maybe there's a coaching position in the future.
