Nathan (elbow) will be activated prior to Sunday's game against the Brewers, MLB.com's Carrie Muskat reports.

EDGE Analysis

The 41-year-old righty has made an admirable return from Tommy John surgery, posting a 3.86 ERA, 0.86 WHIP and 9:5 K:BB in 9.1 innings across Double-A and Triple-A on his rehab assignment. The Cubs have a strong bullpen that could get even stronger at the trade deadline so Nathan will likely be used in fairly low-leverage situations.
