Can we send FPGA device (1ST280EY2F55I2LG) to perform failure analysis?

we found the resistance of pin BC41 (VCCT_GXBL1C) vs pin BB43 (Gnd) is low resistance(23 Ohm) compare good device (286 Ohm). Cisco team need to know the root cause of failure. We have prepare the defect device to INTEL for determining the cause of failure q’ty 1 pcs.
