Cueto (elbow) threw a bullpen session Saturday, Kerry Crowley of The San Jose Mercury News reports.
Cueto is nearly ready to go following last summer's Tommy John surgery. The veteran right-hander was expected to rejoin the rotation last weekend before he experienced some upper-back soreness, but it now looks as though he could start sometime next week, perhaps as early as Tuesday, per Alex Pavlovic of NBC Sports Bay Area.
